STREET-L'AiVi P POST.

SPECIFICATION forming part Of Letters Patent N0. 687,357, dated November 26, 1901. Application filed February 15, 1900. Renewed April 3, 1901. Serial No. 54,228. (No model.)

To a/ZZ whom t may concern:

Be it known that I, HENRY WELLINGTON, a citizen lof the United States, residing at the borough of Brooklyn, city of'New York, in the county of Kings and Stato of New York, have invented certain new and useful Improvements in Street-Lamp Posts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use-the same.

My present invention has relation to posts for street lamps, the same being arranged and adapted for containing a supply of oil or liquid fuel to be fed to the burner by pressure in addition to affording a support for the lamp.

The objects of my invention are to supply a post of the character above indicated which shall be simple and easy of construction, secure against leakage either of air or oil, easy and convenient to charge With fuel and to apply the requisite pressure, and having simple and efficient means for clearing out the sediment, for ascertaining at any time if a sufhcient supply of fuel for one night is contained, for trapping impurities from the fuel, for containing an abundant supply for several nights consumption, and for insuring at least the presence of enough fuel for one night. To accomplish these objects and to secure other and further advantages in the matters of construction, operation, and use, my improvements involve certain new and useful arrangements or combinations of parts and peculiarities of construction, as will be herein first fully described and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure l is a vertical View in section and elevation of a streetlamp post constructed and arranged for operation in accordance With my invention and involving my improvements, a horizontal portion of the post beingbroken out to indicate that it may be of any desired'length or height, the lamp structure and burner being omitted as not essential to purposes of the present description. Fig. 2 is a horizontal section and plan View of the cap, showing the several valves therein. Fig. 3 is a diagraphic view representing the several tubes las if, re-

moved from the post and laid side by side, indicating their varyinglengths, but not their positions in the post.

In all the figures like letters of reference Wherever they occur indicate corresponding parts.

A is the main body of the post, which is in the form of a hollow tube and which may 6o be made of either Wrought or cast metal, but is preferably of Wrought metal. This postis intended to be sunk in the ground to any desired depth and rises above the ground to the height at which it may be desired to maintain the lamp. The interior of the post constitutes a reservoir for `holding a supply of oil or liquid fuel, usually in some form of petroleum, and this in sufficient quantity to last for a Week or more of burning. The reservoir should be made perfectly secure against leakage. To insure this, at the bottom I employ a base B, threaded upon the lower end of the post A and reaching Well up on its exterior. fitted and should be turned on so that the bottom will bear against the lower end of the post. The security of' the joint may be perfected by use of any suitable luting applied The piece B is carefully to the threaded portions, by shrinking the 8o base in place, by rusting, or otherwise, as may be preferred, it being Well understood that petroleum is difficult to confine, and especially so when under pressure.

O is the cap for the post, the saine having a rim O', extending Well dovn upon the post and up to receive a shell, as D, or any other suitable means for mounting the lamp upon the post.

The cap O is provided With a compressible 9o gasket, as o., of any suitable material, the same `beingy located in an .annular channel provided for it in the under side of the cap and situated so that Vthegasket will reach a little beyond the inner and outer surfaces of the Jtop of the post. The rim C is threaded in place upon the top of the post and being turned down hard will cause the gasket to be compressed on the end of the post and in its confining channel or pocket, thus packing the joint at the inside and outside surfaces of the post, as indicated. This makes the joint perfectly secure against leakage of air or other pressure applied to the fuel Within the post,

as is necessary. A central nipple b in the cap C receives a tube E, reaching up into the lamp for sustaining or being connected with the burner, which may be of any proper character, the tube E serving to convey fuel to the burner, which is intended to consume fuel underpressure and is supplied with the usual regulating-valve. A series of tubes depend from the cap into the post. 0f these the cen-- tral one, F, opens into the nipple b and communicates with tube E. It (tube F) stops short of the bottom of the post by a distance sufficient to leave below its lower end an amplel chamber to collect all the sediment,water, or impurities which may be in the oil, so that these matters will not be driven up through tube E. n

The short tube G is for admission of oil to the reservoir and for the introduction of the necessary air or otherpressure. It enters the bottom of cap C and communicates with a channel leading through a boss or enlargement on the cap. This channel is fitted with a plug-valve g, having a reduced inner end with a flat face, adapted to close against the seat provided for it, and having a channel leading angularly from the reduced portion to the exterior. By turning the plug g in, the tube G will bev tightly closed, and by turning it back the tube will be opened. Plug g is supplied with a suitable nipple, as g', for the application of the oil-filling tube and for the pressure-supplyingtube. Theapparatusbeing in proper condition, oil is first introduced through plug g. Then the pressure is applied and the plug closed tightly to its seat.

Tube H terminates within the reservoir at a point above tube G and is used for venting the reservoir when the filling is being accomplished. lt communicates with a channel in the cap the same as tube G, and this channel is governed by a plug-valve h, similar to the one g, save that it is not fitted with a nipple. When this valve is unseated, the filling may proceed; but it must be closed when the pressure is applied.

Tube I is for testing purposes, to determine if 'there be in the reservoira sufficient supply of oil for one nights consumption. It terminates in the reservoir below tubes G and H, but above tube F by a distance which would be great enough to accommodate one nights supply. It enters the cap as do the other tubes, and the channel communicating with it is supplied with a valve t', similar' to the one at h.

When the pressure is on the reservoir, if on opening Ivalve t any oil is forced out kthrough it the attendant is assured that the reservoir is charged 'for one night at least and need not be immediately recharged. This is to'avoid possible failure of the lamp during the night and to obviate unnecessary filling, which consumes time. It is intended that the lamps in a system shall be filled at stated intervals, and the large supply of fuel contained in each post obviates frequent fillment.

ing, at the expense of time and labor, which it is one ofthe chief objects of theinvention to economize. p'

Tube K reaches very near to the bottom of the' reservoir and is intended' only to supply a channel for clearing the reservoir of sedi- Its opening to the exterior through the cap C is governed by a valve k, similar to those previously described. When the pressure is onland valve k opened, the contents of the reservoir will be forced up through the tube K and out through the valve, and when clear enough this valve should be tightly closed. By this means the reservoir may be kept clear of sediment.

When the pressure is applied, the fuel is forced up through tube F and tubeE to supply the burnerfafter the manner of any lamp fed by pressure.

The apparatus is simple, cheap, and effective for all the purposes or objects of the invention previously set forth.

Having now fully described my invention, what I claim as new herein, and desire to secure by Letters Patent, is-

l. Ina street-lamp post arranged to contain a supply of liquid fuel, the combination with the post, of a cap for the same threaded upon its top, said cap being supplied with valves as explained and with a channel for containing a packing-gasket, substantially as shown and described. Y
